BACKGROUND

From prior art dispensing devices of impregnated discs are known, for example impregnated with antibiotics, configured for moving said discs from a dispenser toward a culture plate. These dispensing devices are mainly designed to perform antibiotic sensitivity tests (typically shortened with the acronym AST).

An example of this dispensing device is described in the document EP 2 518 136 B1. This document discloses a particular type of dispensing device comprising a magazine for containers of impregnated discs, able to rotate, which has a shape of circular charger. This magazine comprises a lateral wall in correspondence of which there is a plurality of openings able to allow the extraction of said impregnated discs.

Drawer-like moving means are movable in a radially external direction from a radially-internal position of the magazine to move, each one thereof, a disc impregnated from a bottom portion of a container to an extraction position along said radially external direction.

In EP 2 518 136, the movement of impregnated discs through the device described in the document is slowed down by the presence of drawer-like moving means that come out from the lateral wall of the magazine, to bring the impregnated discs to the extraction position outside of the magazine itself.

The Applicant notes that the presence of drawer-like moving means strongly limits the speed at which it is possible to activate the dispensing device described in EP 2 518 136. These drawer-like moving means, also due to their position substantially internal to the magazine, are complex and need complex mechanical actuators that can compromise the reliability of the dispensing device.

DETAILED DESCRIPTION

In FIG. 1 the reference number 1 identifies as a whole a device for the distribution of impregnable or impregnated supports. This device realizes a system for distributing impregnable or impregnated supports in order to allow to realize antibiotic susceptibility tests (AST).

The device 1 first of all comprises a supporting frame 100 upon which is positioned a dispenser 10 for containers 20 in use containing a plurality of supports 30 impregnable or impregnated with a substantially fluid or liquid substance, optionally comprising a medicament, more particularly and preferably an antibiotic. The dispenser 10 is provided with at least a plurality of seats 11, each of which is configured for housing at least a first container 20. In particular, each of the seats 11 comprises a hole, which preferably, as it can be seen in at least part of the attached figures, has a substantially vertical axis.

In a preferred but non-limiting embodiment, the number of seats 11 housed in the dispenser 10 is equal to 50; this allows to have a large number of containers 20 pre-loaded on the dispenser 10 and allows to keep an automated functioning of the device 1 without the need for further loading of containers 20 for a sufficiently long time. Having a relatively large number of seats 11 in the dispenser 10 allows to make an overall faster functioning of the device 1.

The dispenser 10 may be configured such that the shape and/or size of the seats 11 may be quickly varied. In a preferred embodiment, the dispenser 10 is realized through a plurality of modular elements that allow to adapt the shape and/or size of the seats 11 according to the requirements, thereby allowing an adaptation to containers 20 whose characteristics may be variable according to the specific manufacturer.

Although in the attached figures the seats 11 all have a same size, this should not be understood as limiting. In fact, some embodiments of the device 1, conceived by the Applicant but not represented in detail in the figures attached to the present description, could be provided with seats 11 having different sizes and/or shapes, thus able to house containers 20 of different type.

In particular, in an embodiment, the dispenser 10 is adapted by appropriately configuring at least some of the modular elements or replacing at least some of them, such that the plurality of containers 20 housed comprises a first group of containers 20 of a first type and/or manufacturer and/or shape, and a second group of containers 20 of a second type and/or manufacturer and/or shape. For the purposes of the present disclosure, “shape” of the container 20 means any shape among a shape of a cross-sectional shape of the container 20, in particular a diameter, a length, a width, a depth, a construction material. The modular elements are positioned in a radially outer position of the dispenser 10, but this should not be understood in a limiting manner.

In an embodiment, a modular element comprises at least one seat 11; alternatively, in a further embodiment, a modular element comprises a part of a seat, the remaining part of the seat being formed on a fixed portion of the dispenser 10, not designed to be replaced in use.

Thanks to this technical feature, the use of the dispenser 10 becomes particularly flexible; in fact, it may happen that momentary shortages of supply of containers 20 of a first shape, may lead to the impossibility of completely loading the dispenser 10. Through the configuration of part of the modular elements or the at least partial replacement of themselves, it is possible to provide for a complete loading of the dispenser 10 with heterogeneous containers 20, without affecting the functionality and/or operating performance of the device 1. The replacement or introduction of one or more modular elements also allows a variation of an overall number of seats 11 available on the dispenser 10.

As it will become clear prosecuting the reading of the description, the advantages deriving from the adaptability to containers 20 of different type are particularly important in a device 1 in which the movement of the supports extracted from the containers takes place on a surface of the dispenser 10 that is an upper surface or in any case accessible from above, since in such a case the flexibility deriving from the possibility of extracting supports from containers 20 of different type is maximized by the absence of constraints and/or mechanical parts that is obtained by working on an upper, or accessible from above, surface substantially free.

In an embodiment, the dispenser 10 is in a substantially discoidal shape and detects an upper surface, a lower surface opposite with respect to the upper surface, and a lateral surface interposed between the upper surface and the lower surface. In a non-limiting embodiment, the lateral surface extends along a direction substantially orthogonal with respect to the planes on which the upper surface and the lower surface lie.

FIG. 1 also shows a collector 19 of a movable type, and installed in a supporting castle 19 s, which in turn is supported by the supporting frame 100 of the device 1. Such a collector 19 is configured for collecting at least one support 30 from the dispenser 10 and for transporting the support 30 from the dispenser 10 to a culture plate 40. Although this feature should not be understood in a limiting manner, the supporting frame 100 may be realized in aluminium, so as to be both robust and light.

A first and second conveyor belt 50, 60, for example of a rubberized type, are also shown in the non-limiting embodiment of the device 1 in FIG. 1 . Said first and second conveyor belt 50, 60 are configured for supporting the culture plate 40 and for moving the same at least from an arrival position to a deposit position in which the culture plate 40 is in a position suitable for the deposit of the support 30 transported by the collector 19, and between said deposit position to a destination position in which the culture plate 40 with at least one support 30 is directed for further processing, in particular (but not limited to) for performing the antibiotic susceptibility test. The control of the movement of the first and second conveyor belt 50, 60 is performed by the data processing unit, which sends movement signals to servo actuators, in particular electric motors operatively connected each one to the respective first and second conveyor belt 50, 60. The electric motors may for example be stepper type.

The aforementioned elements are supported by the supporting frame 100, which in an embodiment comprises lateral walls suitable for covering an internal componentry of the device 1 necessary to allow the movement of the various elements thereof described herein, including a data processing unit.

A user interface 100 u is provided at an appropriate height to allow the control of the device 1 by an operator. The user interface 100 u is operatively connected to the data processing unit, preferably but not limited thereto through a wired connection. The supporting frame is also intended to make the user interface 100 u lie at a height convenient for use by an operator of normal height.

Guided user interfaces (GUIs) may be executed on the user interface to allow the operator to control of the functioning of the device 1, in particular a step of loading at least one container 20 on the dispenser 10, in an easy manner, preventing the occurrence of errors. In a non-limiting embodiment, the GUI may guide the operator in scanning an identification code present on the container 20 so that the data processing unit is able to associate determined characteristics of the supports 30 present in the container 20 with the container 20 itself, to perform calibrations and/or configuration adaptations of the device 1 in a substantially automated manner and in association with the specific nature of the supports 30 and/or of the container 20.

As it can be seen from FIG. 2 , in a non-limiting embodiment, the dispenser 10 comprises a plurality of seats 11 arranged in a substantially outer perimeter position and opening on the upper surface. Such seats are preferably aligned along a substantially inclined direction with respect to the plane on which the upper surface of the dispenser 10 lies; in the embodiment shown in the figures, the seats 11 extend axially along a substantially vertical main development axis and orthogonal with respect to the upper surface of the dispenser 10. Preferably, each seat 11 comprises a slotted portion 11a axially extending for at least part of, optionally substantially all of, the extension of the seat 11 along the main development axis.

Although in a perimeter outer position, the seats 11 are aligned on an ideal internal circumference with respect to an outer circumference along which are aligned upper surface portions intended to temporarily retain each at least one respective support 30 extracted from the container 20 in the modes to be described below. For this reason, and for the purposes of the present disclosure, the seats 11 are in substantially correspondence of a first radially internal position 16 of the dispenser 10 and the upper surface portions intended to temporarily hold each at least one respective support 30 are in a second radially outer position 17 of the dispenser 10.

The upper surface of the dispenser 10 comprises a plurality of shaped and/or recessed portions 10 r with respect to a portion 13 of the upper surface lying at a higher height. In correspondence with each of the shaped and/or recessed portions there are the seat 11 and the portion of the upper surface intended to temporarily retain at least one respective support 30 extracted from the container 20. For this reason, it can be asserted that in at least one embodiment, the first position 16 and the second position 17 are in substantial correspondence with the shaped and/or recessed portions 10 r of the upper surface of the dispenser 10.

In an alternative embodiment, not shown in the attached figures, the seats 11 may take a shape of at least partially concave holding elements each one configured for holding a respective container 20 aligned along a substantially vertical direction and at a predetermined distance with respect to a surface of the dispenser 10 that is substantially accessible from above. This, as it will be better clarified by a subsequent reading of the present description, will allow to extract at least one support 30 from the container 20 starting from a bottom portion thereof, but will also allow to move the support 30 by substantially accessing the dispenser 10 from a higher position.

As it can be seen in FIG. 4 , the container 20 has a substantially tubular body suitable for allowing the storage of a plurality of supports 30 in a stack. The body of the container 20, developing along a substantially axial direction, defines a supports unloading portion 20 s that in use lies above the striking portion 24 and that substantially faces the upper surface of the dispenser 10. The supports unloading portion 20 s is opposite with respect to the striking portion 24.

The supports 30, preferably discoidal in shape but not limited thereto, are stacked in the cavity 22 defined by the body of the container 20; said cavity 22 extends along a substantially axial direction. The supports 30 are pushed by a pusher which exerts on the plurality of supports 30 a force axially parallel to an axis of development of the container 20. The pusher is pushed by a spring 21 which is held in correspondence to the striking portion 24 of the container 20 and which is compressed to an increasing extent the more supports 30 are introduced into the cavity 22.

In correspondence with the supports unloading portion 20 s the container 20 has at least one retainer 23 which partially obstructs the cavity 22 and which has an angled portion and arranged in such a way as to stop at least one support 30 which, pushed by the pusher, substantially exits from the tubular body of the container 20 and which can be extracted by pushing or pulling along a substantially oblique direction, in particular orthogonal, with respect to the direction of the push exerted by the pusher.

The device 1 herein described comprises an extractor 18 configured for performing a step of extraction of at least one support 30 from a first container 20, and for moving the support 30 between the first position 16 and the second position 17, which lie in correspondence of the upper surface of the dispenser 10. The extractor is installed on the supporting frame 100.

In use, there is a relative movement between the extractor 18 and the dispenser 10; the relative movement may be a rotational and/or a translational movement. In an embodiment, the extractor 18 is configured for simultaneously extracting a plurality of supports 30 from a respective plurality of containers 20.

As it can be seen in detail in FIG. 1 and FIG. 2 , in a preferred embodiment, but non-limiting thereto, the extractor 18 comprises an extraction finger 18s movable at least between a first position radially internal with respect to the dispenser 10 and a second position radially external with respect to the dispenser 10.

The extraction finger 18 s realizes the aforementioned pusher. As it can be seen from FIG. 3 , the extraction finger 18 s comprises a substantially stepped engagement portion detecting a recess upwardly delimited by a retaining wall and defining a pushing wall substantially oriented along a vertical plane that preferably, but not limited thereto, has a vertical extension at least equal to the thickness of the support 30 to be extracted or greater than the thickness of the support 30 to be extracted. Where the extraction finger 18 s has to simultaneously extract a plurality of supports 30, the vertical extent of the pushing wall will preferably be equal to the number of supports to be extracted simultaneously.

For purposes of the present disclosure, the order of presentation (i.e., the order of extraction) of the supports 30 from the respective container 20 determines the nomenclature “first”, “second”, and so on, for the respective support 30. Thus, a first container 20 will have a first support 30 (in use the first to be extracted) stacked on a second support 30 (in use, the second to be extracted), and so on. A second container 20 will have a first support 30 (in use, the first to be extracted), stacked on a second support 30 (in use, the second to be extracted), and so on.

In the embodiments shown in the figures, the movement of the extraction finger 18 s is a substantially axial translation along a movement axis Z radial with respect to the center of the dispenser 10. In use, during the translation, the extraction finger 18 s moves from the first radially internal position to the second radially external position and, being at substantially the same height at which the support 30 is located, engages at least one support 30 from the container 20; at this point, the support 30 is still substantially in the first position 16. After the engagement, the support 30 is extracted from the first container 20, retained in a fixed position in the respective seat, and is dragged in substantial sliding within the shaped and/or recessed portion 10 r along the movement axis Z, moving from the first position 16 to the second position 17 being pushed by the extraction finger 18 s.

In an alternative configuration, not shown in the attached figures, the extraction finger 18 s may be configured for extracting the support 30 from the container 20 by means of a traction towards a direction radially external with respect to the center of the dispenser 10. In such a case, in use, during the translation the extraction finger 18 s moves from the first radially internal position towards the second radially external position and engages at least one support 30 from the container 20; at this point the support 30 is substantially still in the first position 16. After the engagement, the support 30 is dragged in substantial sliding within the shaped and/or recessed portion 10 r along the movement axis Z, moving from the first position 16 to the second position 17 being pulled by the extraction finger 18 s. The extraction by traction may also occur along a radially internal direction.

In correspondence of the second position 17, on the upper surface of the dispenser 10 there is, and opens, a holding hole 14, which is connected to a first vacuum holder 14 v configured for drawing air from the upper surface of the dispenser 10 through the holding hole 14. A vacuum pump is operatively connected with a first vacuum holder 14 v.

In particular, the holding hole 14 is positioned within the shaped and/or recessed position and extends along an at least partially vertical direction. The area around the holding hole 14 acts as a striking surface when the vacuum is exerted on the bottom surface of the support 30.

When a support 30 arrives in correspondence of the holding hole, it is held by means of a vacuum. In this way, it is ensured that a precise position of the support 30 is maintained.

It is noted that the presence of the vacuum holder is not necessarily linked to the presence of all the above-described technical features, since the Applicant has in particular conceived an embodiment of the device 1 which comprises:

-   a dispenser 10, provided with a plurality of seats 11 configured for     housing a corresponding plurality of containers 20, each one     containing a plurality of supports 30 impregnable and arranged in a     stack; -   an extractor 18, positioned in substantial correspondence of the     dispenser 10 and/or operatively associated with the dispenser 10 and     configured for extracting at least one first support 30 from a first     container 20 housed in a respective seat 11 of the dispenser 10, and     for moving the first support 30 between a first position 16 within     the first container 20 and a second position 17 extracted from the     first container 20; -   a collector 19, configured for collecting the first support 30 from     the second position 17 and for transporting the first support 30     from the second position 17 towards a culture plate 40;

and wherein the device 1 comprises at least one first vacuum holder 14 v configured for creating a vacuum between a striking surface and the first support 30, wherein the vacuum holder is configured for holding the at least one first support 30 in substantial correspondence of the second position 17 and/or of the collector 19.

Two contiguous shaped and/or recessed portions 10 r will have a respective holding hole 14, each one operationally connected to the first, and respectively second, vacuum holder.

The striking surface may be the upper surface of the dispenser 10, in particular in correspondence of the shaped and/or recessed portion 10 r, or a surface of the dispenser 10 accessible from above, or as it will be better clarified in the following portion of the description a collection area of an auxiliary dispenser 10 w.

The dispenser 10 rotates around its central axis with a controlled rotation set by an automatically controlled rotor, so that a second seat 11 is positioned in a position such that to allow the extraction of a further support 30 from a second container 20. In use, therefore, a first step of extraction of a first support 30 from the first container 20 is followed by a step of extraction of a first support 30 from the second container 20. In fact, in a non-limiting embodiment, the dispenser 10 is a rotatable dispenser, the rotation of which is controlled by a rotor preferably installed below the bottom surface of the dispenser 10. The data processing unit controls the actuation of the rotor so as to allow said controlled rotation. In particular, it is noted that the rotation may be clockwise or counter clockwise.

After the rotation of the dispenser 10, the device 1 is configured for performing a movement of the extraction finger 18 s in the form of a substantially axial translation along a movement axis Z radial with respect to the center of the dispenser 10. In use, during the translation, the extraction finger 18s moves from the first radially internal position towards the second radially external position and engages at least one support 30 from the container 20; at this point, the support 30 is substantially still in the first position 16. After the engagement, the support 30 extracted from the second container 20 is dragged in substantial sliding within the shaped and/or recessed portion 10 r moving from the first position 16 to the second position 17 being pushed by the extraction finger 18 s. A further creation of the vacuum allows the appropriate holding of the support 30 extracted from the second container 20.

Alternatively to the above, in an alternative embodiment, the dispenser 10 is kept in a fixed position, and it is the extractor 18 that rotates, in use, with respect to the dispenser 10 to first extract a first support 30 from the first container 20 along said radially external direction and, subsequently to extract a first support 30 from the second container 20 along said radially external direction after a rotation of the extractor finger by an angle sufficient to position itself in correspondence of the second seat 11.

Still, in an alternative embodiment, the extractor 18 may be configured for simultaneously extracting a first support from a first container 20 and a first support 30 from a second container 20. This is possible both in the case where it is the dispenser 10 that rotates relative to the extractor 18, and in the case where it is the extractor 18 that rotates with respect to the dispenser 10, this time fixed.

As it is shown in FIG. 5 , the Applicant has conceived an alternative embodiment form for the dispenser 10, wherein the plurality of seats 11 suitable for housing, each one, a container 20 is arranged on an ideal circumference radially external with respect to the ideal circumference in correspondence to which the upper surface portions intended to temporarily retain at least one respective support 30 extracted from the container 20 are positioned. In such a case, the first position 16 is radially outermost with respect to the second position 17. The embodiment of the dispenser 10 of FIG. 5 may be associated with an extractor 18 whose extraction finger 18 s is configured for working pushing or, alternatively pulling, thus pushing or pulling the support 30. The Applicant believes that the description of these two working modes for the extractor 18 has been previously exhaustively described, and for this reason does not repeat the description of them again herein, referring the reader to the preceding paragraphs. However, unlike previous embodiments in which the movement of the at least one first support 30 takes place along a radially external direction, in case of the embodiment of FIG. 5 , this movement occurs along a radially internal direction of movement.

A collector 19 is configured for collecting the support 30 from the second position 17 and for transporting the support 30 from the second position 17 towards a culture plate 40. FIGS. 6 through 9 show successive steps of a movement of the collector 19 to perform the transportation of the support 30.

FIG. 6 shows a perspective view of a configuration wherein the collector 19 is in the process of extracting a support 30 from the dispenser. In FIG. 6 , the extraction finger 18 s is in the second radially external position, and has pushed a support 30 in correspondence of the holding hole so that said support 30 is retained by means of the vacuum. In fact, it should be noted that in correspondence of the extraction finger indicated by the numerical arrow reference 18 s, the shaped and/or recessed portion at the holding hole is not shown, and this is a sign that the support 30 is in the second position 17.

The collector 19 is axially aligned above the dispenser 10 and, in particular, is axially aligned above the second position 17 in correspondence of which is located the support 30 that has been pushed by the extraction finger 18 s. The first conveyor belt 50 has been moved so that the culture plate 40 is in substantial correspondence of the dispenser 10 and, in particular, is aligned with the axis Z which radially departs from the center of the dispenser 10 passing through the first position 16 and the second position 17, in particular passing through the center of the seat 11 and the center of the holding hole 14. As it can be seen from FIG. 6 , the culture plate 40 is empty.

As shown in FIG. 7 , subsequently the collector 19 performs an axial translation movement along the axis W, substantially vertical, in order to approach, accessing from above, the dispenser 10 so as to be able to collect the support 30 from the second position 17. In detail, when it is arrived in correspondence of the second position 17, and in particular having a collection head 19 t in substantial contact with the support 30, an auxiliary vacuum holder is activated to exert a vacuum between an upper surface of the support 30 and the collector 19, so that the support 30 can be firmly retained in substantial correspondence of a lower end portion of the collection head 19 t. This vacuum is sufficient to lift the support 30 from the shaped and/or recessed portion 10 r. Thus, the device 1 comprises an auxiliary vacuum holder 19 v operatively connected to the collection head 19 t, which allows the holding of the support 30 for a predetermined period of time in correspondence of the collection head 19 t.

The auxiliary vacuum holder comprises at least one duct operatively connected to said vacuum pump and comprises a hole opening on the lower end portion of the collection head 19 t. Said lower end portion of the collection head 19 t may have a substantially planar configuration or, alternatively, may be provided with a recess whose shape is preferably tracing that of the support 30.

In substantial correspondence of the instant of time in which the auxiliary vacuum holder 19 v is activated, the first vacuum holder 14 v operatively connected with the holding hole 14 on the dispenser 10 is deactivated, or otherwise placed in a configuration such that a vacuum is no longer exerted between the dispenser 10 and the support 30. For this reason, it may therefore be understood that the activation of the first vacuum holder 14 v and of the auxiliary vacuum holder is alternative. The data processing unit controls the alternation of the activation and deactivation of the first vacuum holder 14 v and of the auxiliary vacuum holder.

In order to allow an effective extraction of the support 30, when the collector 19 performs the aforementioned translational movement along the axis W, the extraction finger 18 s is retracted to a position radially internal with respect to the dispenser 10; this configuration is well shown in FIG. 7 .

Subsequently, the collector 19 is raised through an axial translation movement along the axis W and then axially translated along a direction substantially parallel to the axis Z that radially departs from the center of the dispenser 10.

The translation of the collector along the aforementioned direction is such that it radially departs from the center of the dispenser 10. The vacuum is kept during the raising along the axis W and the translation along the direction substantially parallel to the axis Z so that the support 30 can be firmly retained in substantial correspondence of an upper surface thereof on the collection head 19 t of the collector 19.

In FIG. 8 is shown a subsequent step wherein the collector 19 is in substantial axial alignment above the culture plate 40 and retains the support 30 by means of the previously created vacuum. In particular, FIG. 8 shows a configuration wherein the collector 19 is at a height such that it brings the support 30 into substantial contact with the culture plate 40. At this point, the vacuum is released by means of a deactivation of the pump or closing of the valve of the collector 19. The support 30 is now deposited on the culture plate 40.

At this point, as it is shown in FIG. 9 , the collector 19 is raised by means of an axial translation movement along the axis W and then axially translated along a direction substantially parallel to the axis Z, in particular radially approximating the center of the dispenser 10 until it reaches a substantial alignment with the second position 17. FIG. 9 shows a configuration in which the dispenser 10 has been rotated in a counter clockwise direction by means of a rotation set by the data processing unit on the rotor. With such a rotation, a new support 30 can be extracted from another container 20. In fact, it can be observed from FIG. 9 that the container 20 which is on the right of the collector 19 is empty. In particular, in FIG. 9 the device 1 is shown in a particular instant of time of its working cycle in which the extraction finger 18 s has already been moved in a radially external direction along the axis Z in order to push a new support 30 (i.e., the first support 30 of a second container) from the first position 16 to the second position 17.

In order to allow a deposit of a new support 30 on the culture plate 40, this culture plate 40 must be rotated. A rotor disk 80, positioned below the culture plate 40, or alternatively a rotating prehension device, perform a controlled rotation of the culture plate 40 around a substantially vertical axis. The rotor disk 80 or the rotating prehension device are controlled by the data processing unit. The rotor disc 80 or the rotating prehension device may be moved away from and/or approaching the culture plate 40, so that it is possible a release of the culture plate 40 for subsequent movements.

FIG. 10 shows a flowchart summarizing the functioning of the device 1 according to FIGS. from 6 to 9 ; in detail, the block 1000 identifies the positioning of at least a first container 20, containing a plurality of supports 30 arranged in a stack, in a first seat 11 of a rotatable dispenser 10. If the dispenser 10 possesses a plurality of seats 11 as in the case of the non-limiting embodiment shown in FIGS. from 6 to 9 , there will be further steps of positioning of a second, or more, container(s) in a respective seat 11 of the dispenser 10.

The aforementioned positioning (block 1000) may be performed manually by an operator or, alternatively, may be performed by a servo actuator of the device 1. Thus, in an embodiment, the step of positioning of the at least one first container 20 is controlled by a data processing unit, in particular by a data processing unit of the device 1.

In a non-limiting embodiment, the positioning of the container 20 in the seat 11 comprises the introduction of it along an axial direction substantially aligned with the direction along which the seat 11 is developed. In the case of the embodiment shown in the attached figures, the direction of the introduction of the container 20 is substantially vertical.

In a particular embodiment, the positioning of the container 20 in the seat 11 causes the supports unloading portion 20 s of the first container 20 to face upwards and substantially face the upper surface of the dispenser 10, such that a support 30 faces at a height substantially aligned with the height at which the shaped and/or recessed portion 10 r lies. In a further embodiment, the different location of the seats 11 causes the supports 30 unloading portion of the first container 20 to face downwards, and still face on the upper surface of the rotatable dispenser.

Once the filling partial or total of the seats 11 with a respective container has been completed, a step of extraction of at least one support 30 from one of the containers 20 present in the dispenser 10 may take place. Such step of extraction is schematically represented by the block 1001 of FIG. 10 .

The extraction of the support 30 firstly comprises the activation of the extractor 18 and comprises, after said activation, a movement of the support 30 between the first position 16 and the second position 17, in particular where the first and second position 16, 17 lie substantially in correspondence of the surface of the dispenser 10. The movement is represented by the block 1002 of the diagram of FIG. 10 . More generally, the movement of the support 30 takes place between said first position 16 and said second position 17 where at least one between the first position 16 and said second position 17 lies substantially in correspondence of a height comprised between at least half of the vertical development of the dispenser 10 and a height substantially corresponding to the height at which the upper surface of the dispenser 10 is located and/or wherein the first position 16 and the second position 17 are accessible from a direction substantially inclined with respect to a direction of extraction of the support 30, in particular being accessible from above, and face the outside of the dispenser 10.

The Applicant particularly observes that the step of extraction (block 1001) of the support 30 from the container 20 is followed by the movement (block 1002) because in at least one alternative and non-limiting embodiment, the movement realized by the extractor 18 to cause the extraction of the support 30 from the container 20, by specific construction of the support 30, the container 20 and/or by conformation or direction of orientation of the seat 11, may imply a movement significantly distinguishable with respect to the nearly linear translation of the support 30 realized by means of the extractor finger 18 s in the embodiment represented in FIGS. from 6 to 9 .

After the motion of the holder 30, a step of transportation of the support 30 from the dispenser 10 toward a culture plate 40 takes place; this step of transportation is identified by the block 1004 in FIG. 10 . There is a step of actuation of the collector 19 to collect the support 30 from the second position 17 and a step of transportation, described above, performed by the collector 19, to transfer the support 30 from the dispenser 10 to the culture plate 40.

The block 1005 identifies a step of rotation of the culture plate 40 to allow a new deposition of a new support 30. The rotation of the culture plate 40 is preferably controlled by a data processing unit of the device 1. The device 1 is configured for extracting a predefined number N of supports from the dispenser 10 to deposit them on the culture plate 40. For example, such predefined number N may be equal to the number of supports that may be supported on the culture plate 40. The device 1 herein described is preferably configured for checking (block 1006) whether the number of supports 30 extracted from the dispenser 10 is equal to N.

In affirmative case (output S of block 1006), the operational cycle of extraction of supports 30 from the dispenser 10 ends and the culture plate can be translated towards the target position through the first and/or second conveyor belt 50, 60.

In negative case (output N of block 1006), the operational cycle of extraction of supports 30 from the dispenser continues and (block 1007) a rotation of the dispenser 10 takes place so that a subsequent container 20 (or equivalently a further seat 11), be in a predefined position intended to allow the extraction of the at least one support 30 from the subsequent container 20 by means of the extractor 18.

The block diagram of FIG. 11 shows an operating cycle of an alternative embodiment for the device 1 herein described. Also in this embodiment, the block 1000 identifies the positioning of the at least one first container 20, containing a plurality of supports 30 arranged in a stack, into a first seat 11 of a rotatable dispenser 10. If the dispenser 10 possesses a plurality of seats 11 as in the case of the non-limiting embodiment shown in FIGS. from 6 to 9 , further steps of positioning of a second, or more, container(s) into a respective seat 11 of the dispenser 10 will be present.

In a non-limiting embodiment, the positioning of the container 20 in the seat 11 comprises the introduction thereof along an axial direction substantially aligned with the direction along which the seat 11 itself is developed. In the case of the embodiment shown in the attached, the direction of introduction of the container 20 is substantially vertical.

Once the filling partial or total of the seats 11 with a respective container has been completed, a step of extraction of at least one support 30 from one of the containers 20 present in the dispenser 10 may take place. This step of extraction is schematically represented by the block 1001 of FIG. 10 .

The extraction of the support 30 firstly comprises the activation of the extractor 18 and comprises, after said activation, a movement of the support 30 between the first position 16 and the second position 17, in particular where the first and second position 16, 17 lie substantially in correspondence of the surface of the dispenser 10. The movement is represented by the block 1002 of the diagram of FIG. 9 . More generally, the movement of the support 30 takes place between said first position 16 and said second position 17 where at least one between said first position 16 and said second position 17 lies substantially in correspondence of a height comprised between at least half of the vertical development of the dispenser 10 and a height substantially corresponding to the height at which there is the upper surface of the dispenser 10 and/or wherein the first position 16 and the second position 17 are accessible from above and face the outside of the dispenser 10.

Again, the Applicant particularly observes that the step of extraction (block 1001) of the support 30 from the container 20 comprises the movement (block 1002) because in at least one alternative and non-limiting embodiment, the movement realized by the extractor 18 to cause the extraction of the support 30 from the container 20, by specific construction of the support 30, of the container 20 and/or by conformation or direction of orientation of the seat 11, may imply a movement significantly distinguishable with respect to the nearly linear translation of the support 30 realized by the extractor finger 18 s in the embodiment represented in FIGS. from 6 to 9 .

The device 1 is configured for causing the movement of a plurality of supports 30 from the first position 16 to the second position 17 before proceeding with the transportation of the supports so moved toward the culture plate 40. In particular, the device 1 is configured for causing a movement of a predetermined number M of supports 30 from the first position 16 to the second position 17 before proceeding with transporting the M supports 30 so moved toward the culture plate 40.

For this reason, block 1003 identifies a step of checking whether the number of supports 30 moved from the first position 16 to the second position 17 is equal to M.

In negative case (block 1003, output N), a rotation of the dispenser 10 is performed (block 1008), so that a new container 20 (or equivalently a new seat 11), is in a predefined position intended to allow the extraction of the at least one support 30 from the next container 20 by means of the extractor 18.

In affirmative case (block 1003, output S), a step of transportation of the at least one support 30 from the dispenser 10 toward a culture plate 40 is performed; this step of transportation is identified by block 1004 in FIG. 10 . There is a step of actuating the collector 19 to collect the at least one support 30 from the second position and a step of transportation, described above, performed by said collector 19 to transfer the support 30 up to the culture plate 40.

In particular, it is noted that the expression “transportation of the at least one support 30” implies that in one embodiment the collector 19 is operated to collect a support 30 from the second position, and lay it on the culture plate 40, and again return in a position of substantial axial alignment to a second position 17 to collect a subsequent support 30.

In this case, the dispenser 10 is again rotated by its rotor to allow the access of the collector 19 to a second position 17 contiguous with that from which the support 30 deposited on the culture plate 40 was collected. After each new deposition of a support 30 on the culture plate 40, the latter is rotated with a controlled rotation. Alternatively, the dispenser 10 may be kept in a determined and fixed position while the collector 19 performs a plurality of cycles of collection and subsequent deposition of supports 30 onto the culture plate 40. In the latter case, however, the collector 19 will be configured for performing a composite movement wherein the horizontal translation cannot be longer merely axial along a direction radial with respect to the center of the dispenser 10, but must be a horizontal translation along a direction substantially inclined with respect to said radial direction to reach, at each collection cycle, a second position 17 different from the previous one, until a number M of supports movement cycles is reached. Still alternatively, the collector 19 may be configured for performing a translational movement along a direction radial with respect to the center of the dispenser 10, and for performing a rotation sufficient to position itself in a plurality of second positions 17 for the collection of the supports 30. It thus appears clear that the movement executable by the collector 19 is a composite movement.

In an alternative embodiment, the collector 19 is actuated to simultaneously collect a plurality of supports 30 from a plurality of second positions 17 on the dispenser 10 and then deposit said plurality of supports 30 on the culture plate 40.

The block 1005 identifies a step of rotation of the culture plate 40 to allow a new deposition of a new support 30 collected from the dispenser 10, on said culture plate 40.

The device 1 is configured for extracting a predefined number N of media from the dispenser 10 to deposit them on the culture plate 40. For example, said predefined number N may be equal to the number of supports that may be supported on the culture plate 40. Preferably, the device 1 described herein is configured for checking (block 1006) whether the number of supports extracted from the dispenser 10 is equal to N.

In affirmative case (output S of block 1006), the operational cycle of extraction of supports 30 from the dispenser 10 ends and the culture plate may be translated towards the target position by the first and/or second conveyor belt 50, 60.

In negative case (output N of block 1006), the operational cycle of extraction of supports 30 from the dispenser continues and (block 1007) a rotation of the dispenser 10 takes place, so that a new container 20 (or equivalently a new seat 11), is in a predefined position intended to allow the extraction of the at least one support 30 from the next container 20 by means of the extractor 18. In particular, it is noted that in the case where the collector 19 is configured for simultaneously collecting a plurality of M supports 30, the rotation of the dispenser 10 occurs for an M number of “jumps” in order to reach an M-th second position 17, or equivalently, an M-th contiguous seat 11.

An alternative embodiment of the device 1 is shown in FIG. 12 . In this embodiment, it is observed the presence of only one conveyor belt 50 and a translator which transports the culture plate 40 from a starting position to the conveyor belt by means of a rotational movement around a sensibly vertical axis and/or substantially parallel to the axis Y.

In the embodiment of FIG. 12 , the dispenser 10 comprises a plurality of seats 11 arranged in a substantially perimeter outer position and opening on the upper surface. Preferably, such holes are aligned along a direction substantially inclined with respect to the plane on which the upper surface of the dispenser 10 lies; in the embodiment shown in the figures, the seats 11 extend axially along a substantially vertical main development axis and orthogonal with respect to the upper surface of the dispenser 10. Preferably, each seat 11 comprises a slotted portion 11 a axially extending for at least part of, optionally substantially all of, the extension of the seat 11 along the main development axis.

In contrast to the embodiment previously shown, in the embodiment of FIG. 12 , the second position 17 wherein the support 30 is retained before being transported on the culture plate 40 is not on the dispenser 10 but is on an auxiliary dispenser 10 w, which is mounted on the supporting frame 100 and has a plurality of collection areas 10 r′ preferably arranged in a substantially perimetral outer position and are on the upper surface of the auxiliary dispenser itself. In the embodiment of FIG. 12 , this auxiliary dispenser 10 w has a substantially circular shape. This should not be understood in a limiting way, since the auxiliary dispenser 10 w may assume a plurality of different shapes, for example and in a non-limiting extent rectangular.

The upper surface of the auxiliary dispenser 10 w is substantially planarly aligned with the upper surface of the dispenser 10 (in particular, there is an alignment on a substantially identical horizontal plane) so that a movement of the element 30 extracted from the container 20 can be realized by substantially sliding on the upper surface of the dispenser 10, starting from a first position 16, to reach the upper surface of the auxiliary dispenser 10 w. In correspondence of said collection areas 10 r′, the auxiliary dispenser 10 w comprises respective holding holes 14, preferably in a number equal to one for each collection area 10 r′, which allow to create a vacuum with the lower surface of the support 30 when positioned in correspondence of the area itself.

The auxiliary dispenser 10 w is movable; in the specific embodiment visible in FIG. 12 and FIG. 14 , the auxiliary dispenser 10 w is rotating, and rotates around an axis substantially vertical and parallel to the axis Y. The axis of rotation of the dispenser 10 and the axis of rotation of the auxiliary dispenser 10 w are therefore parallel. The rotation of the auxiliary dispenser 10 w is synchronized with the rotation of the dispenser 10 so that a determined collection area 10 r′ of the upper surface of the auxiliary dispenser 10 w is radially aligned with a certain seat 11 of the dispenser 10.

In a preferred, but non-limiting, embodiment, the auxiliary dispenser 10 w is placed in rotation by its own rotor which is operatively connected with a data processing unit of the device 1 which also controls the rotation of the dispenser 10. Alternatively, there may be a single rotor for the auxiliary dispenser 10 w and for the dispenser 10, which transmits a rotational motion to both the auxiliary dispenser 10 w and the dispenser 10 by means of rotation demultiplying means (gears, belt drives on pulleys of suitable radius).

In this case, in use, the extraction finger 18 s during its movement between the position radially internal with respect to the center of the dispenser 10 and the position radially external with respect to the center of the dispenser pushes the support 30 from the first position 16 (on the upper surface of the dispenser 10) to the second position 17 of the collection area 10 r′ of the auxiliary dispenser 10 w.

In particular, a non-limiting embodiment of the auxiliary dispenser 10 w is shown in FIG. 14 , which has a perimeter ring 10 p that identifies a substantially central daisy-shaped hole, having a plurality of recesses each one defining a convexity facing the radially outermost portion of the auxiliary dispenser 10 w. The number of recesses is equal to the number of collection areas 10 r′, and each recess lies substantially in correspondence of a respective collection area 10 r′. In a preferred, non-limiting embodiment, below the perimeter ring 10 p is provided a slit that substantially develops along at least part of, preferably all, the perimeter of the auxiliary dispenser 10 w.

In use, during the motion of the support 30 between the first and second position, the extraction finger 18 s pushes the support 30 through the slit and causes it to arrive in correspondence of the second position 17, where there is the collection area 10 r′.

The rotation of the auxiliary dispenser 10 w takes place after the step of movement of the at least one first support 30 from the first position 16 in correspondence of the container 20 towards the second extracted position 17, which is therefore in correspondence of the collection area 10 r′ on the auxiliary dispenser 10 w.

Therefore, the device 1 may be configured and programmed to cause that after the movement of the support 30, a step of transportation of the at least one first support 30 from the dispenser 10 towards a culture plate 40 takes place. There is a step of actuation of the collector 19 to collect the support 30 from the second position 17, thus from a predetermined collection area 10 r′ on the auxiliary dispenser 10 w to collect the support 30 from the auxiliary dispenser 10 w and to perform a transportation by which the support 30 is transferred from the auxiliary dispenser 10 to the culture plate 40.

In particular, the device 1 is configured for depositing the plurality of supports 30 on the auxiliary dispenser 10 w such that said plurality of supports assume a substantially aligned configuration on an imaginary circumference. Clearly, such a configuration aligned on an imaginary circumference should not be construed in a limiting manner.

The collector 19 may be configured for extracting at least part of the plurality of supports 30 arranged on the auxiliary dispenser 10 w in a simultaneous manner, and for performing the step of transportation (block 1004) of the plurality of supports from the auxiliary dispenser 10 w toward the culture plate 40 in a single operation of movement. Thus, in one embodiment, the collector 19 collects two or more, but still only a portion of, the supports 30 from the auxiliary dispenser 10 w; in an alternative embodiment, the collector 19 may be configured for collecting all of the supports 30 present on the auxiliary dispenser 10 w.

In this case, the collector 19 comprises a plurality of collection heads 19 t, each of which has its own hole connected to a vacuum pump by means, preferably, of a respective solenoid valve. Alternatively, all of the collection heads are connected to a vacuum pump by means of a single solenoid valve, common for all of the heads. Further alternatively, all collection heads are connected to the vacuum pump without solenoid valves.

The Applicant observes that the recesses defined on the ring 10 p, each one, have a shape substantially tracing part of the external shape of the collection heads 19 t. Although such collection heads are not visible in FIG. 14 , these collection heads will preferably assume a substantially circular shape. The purpose of the ring 10 p, and in particular of each of the recesses, may therefore also be considered defining an external guide during the last portion of substantially vertical stroke that the collection heads of the collector 19 execute before extracting the support 30, or the plurality of supports 30, from the respective collection area 10 r′. In this way, a greater extraction accuracy of each support 30 is provided, even if the collection heads must perform a long stroke.

It should be noted that a same collector 19 may be configured for alternately collecting part or all of the supports 30 from the auxiliary dispenser 10 w. In particular, should the collection take place with the exercise of a vacuum on the upper surface of the supports 30 arranged on the auxiliary dispenser 10 w, it will be sufficient to selectively activate, by opening or closing the respective solenoid valve, the vacuum holder for one or more of the collection heads 19 t of the collector 19, to cause depending on the selection made the collection of part of, or all, the supports 30 present on the auxiliary dispenser 10 w. The activation of the vacuum holder takes place through the data processing unit.

Should the diameter of the auxiliary dispenser 10 w be substantially similar to the diameter of the culture plate 40, the arrangement of the plurality of supports 30 on the auxiliary dispenser 10 w will be the same as the one assumed by the plurality of supports 30 on the culture plate 40. Thanks to this aspect, it is possible to speed up the transfer of supports 30 on the culture plate 40, and at the same time simplify the structure of the collector 19.

In the latter case, the collector 19 is configured for performing a composite movement in order to transfer the plurality of supports 30 simultaneously on the auxiliary dispenser 10 w. In the specific embodiment shown in the attached figures, said movement comprises a rotation about a substantially vertical axis and a translation substantially in turn along a substantially vertical axis in order to allow the approaching and moving away of the collector 19, in particular of the collection head 19 t respectively to, and from, the auxiliary dispenser 10 w or to, and from, the culture plate 40. In an alternative embodiment provided for by the Applicant but not shown in the attached figures, the collector 19 does not rotate but translates axially from a position substantially above the auxiliary dispenser 10 w to a position substantially above the culture plate 40. For this reason, in that case the collector 19 will be configured for performing a composite movement comprising two translations along, respectively, a first and a second axis substantially inclined to each other, and in practice orthogonal, for allowing the approaching and the moving away of the device to, and from, respectively, the auxiliary dispenser 10 w or to, and from, the culture plate 40 and for moving horizontally between the auxiliary dispenser 10 w and the culture plate 40.

The Applicant observes that where on the auxiliary dispenser 10 w the supports 30 are temporarily held by means of a vacuum, any rapid movements of the auxiliary dispenser 10 w in particular rotational and/or translational movements can be performed without fear of undue displacement of one or more supports.

The block diagram of FIG. 13 shows a specific embodiment of the method performed by the device of FIG. 12 .

The block 1000 identifies the positioning of at least a first container 20, containing a plurality of supports 30 arranged in a stack, in a first seat 11 of a rotatable dispenser 10. If the dispenser 10 possesses a plurality of seats 11 as in the case of the non-limiting embodiment shown in FIGS. from 6 to 9 , further steps of positioning of a second, or more, container(s) into a respective seat 11 of the dispenser 10 will be present.

After a filling partial or total of the seats 11 with a respective container has been completed, a step of extraction of at least one support 30 from one of the containers 20 present in the dispenser 10 may take place. Such a step of extraction is schematically represented by the block 1001.

The extraction of the support 30 firstly comprises the activation of the extractor 18 and comprises, after said activation, a movement of the support 30 between the first position 16 and the second position 17. The movement is represented by the block 1002 of the diagram of FIG. 13 . In particular, in a first configuration, the dispenser 10 is positioned in a first position from which a support 30 is extracted from a first container 20 and is extracted by means of the extraction finger 18 s from the first container 20 and is pushed into a first collection area 10 r′ of the auxiliary dispenser 10 w.

The block diagram of FIG. 13 identifies with M a predetermined number of supports 30, which may be equivalent to the number of collection areas 10 r′ of the auxiliary dispenser 10 w. The block 1003 identifies a step of verification of whether the number of supports 30 moved from the first position 16 to the second position 17 is equal to M.

In negative case (block 1003, output N), the auxiliary dispenser 10 w is rotated (block 1009) by a determined angle so that a new and empty collection area 10 r′ is substantially aligned with the direction of extraction identified by the axis Z.

In particular, during the rotation of the auxiliary dispenser 10 w a vacuum is created through the holding holes 14 so that an appropriate holding of the at least one support 30 positioned in substantial correspondence of the respective at least one collection area 10 r′, part of the surface of which is a striking surface for the support 30 can be exercised.

Before the extraction of a new support 30, the dispenser 10 is moved, in particular rotated, to align a second container 20 radially on the extraction direction identified by the axis Z.

The rotation of the dispenser 10 with respect to the auxiliary dispenser 10 w can take place: simultaneously with the rotation of the auxiliary dispenser 10 w, before the rotation of the auxiliary dispenser 10 w or after the rotation of the auxiliary dispenser 10 w (block 1008). Thus, a new support 30 is extracted from the second container 20 and is extracted through the extraction finger 18 s from the second container 20 and is pushed into the new collection area 10 r′ of the auxiliary dispenser 10 w.

Alternatively, in a second configuration, the dispenser 10 is positioned in a first position from which a support 30 is extracted from a first container 20, is extracted by means of the extraction finger 18 s from the first container 20 and is pushed into a first collection area 10 r′ of the auxiliary dispenser 10 w. Subsequently, the auxiliary dispenser 10 w is rotated for a determined angle so that a new and empty collection area 10 r′ is substantially aligned with the extraction direction identified by the axis Z. Then, a new support 30 is extracted by means of the extraction finger 18 s from the first container 20 and is pushed into the new collection area 10 r′ of the auxiliary dispenser 10 w. It is observed that in this case the dispenser 10 is not moved. Therefore, it is observed that the step of rotation of the dispenser 10 is not always present at every rotation of the auxiliary dispenser 10 w, and for this reason the block 1008 is represented with a dashed line.

In affirmative case (block 1003, output S), a step of transportation of the plurality of M supports 30 is performed from the auxiliary dispenser 10 w toward the culture plate 40; this step of transportation is identified by the block 1004 in FIG. 13 . There is a step of actuation of the collector 19 to collect the at least one support 30 from the second position and a transportation, described above, performed by said collector 19 to transfer the plurality of M supports up to the culture plate 40.

Optionally, particularly should the plurality of M supports transported on the culture plate 40 said culture plate 40 be not completely filled, a step of rotation or more generally, movement of the culture plate 40 (block 1005) is performed.

Thanks to the operational flexibility offered by the embodiment of the device 1 wherein the auxiliary dispenser 10 w is present, and assuming that different containers contain, each one, a plurality of supports 30 impregnated with a first antibiotic (first container 20) and with a second antibiotic (second container 20), it is possible to load the auxiliary dispenser 10 w in an extremely efficient and easily alterable way, during two or more loading cycles, with supports 30 impregnated with the same antibiotic or with a different antibiotic.

Although this shall not intended to be limiting, the device 1 may have a movable arm 70 configured for removing and repositioning a cover on the culture plate 40. In detail, said movable arm 70 is controlled by the aforementioned data processing unit; said data processing unit may be configured or programmed to cause the covering of the culture plate 40 upon completion of the filling of said culture plate, or even only when the culture plate 40 is partially filled with supports 30.

The previously mentioned data processing unit may comprise a general-purpose processor on which a predetermined software program designed to allow the execution of the operating cycle of the device 1 described herein is executed. This program may be written in any programming language. The data processing unit may further comprise one or more ASIC-type processors configured for allowing the execution of the operating cycle of the device 1 herein described.

Further alternatively, the data processing unit may be, or comprise, a programmable logic controller (PLC). The software program may be stored in a non-transitory memory, and such memory is integrated into the data processing unit or otherwise is operationally accessible from the data processing unit through any type of connection, whether electrical, optical or wireless.

Finally, the Applicant notes that the device 1 that is the object of the present disclosure may further comprise an optical control system, configured for, and intended to, verifying the correct positioning of the supports 30 during at least part of the steps of transfer from the respective containers 20 to the culture plate 40 and further configured for verifying the presence and/or the correct positioning of the supports 30 on the auxiliary dispenser 10 w. In a preferred, but non-limiting, embodiment, this optical control system is controlled, in particular at least activated and/or deactivated, through the aforementioned data processing unit.

More in detail, the optical control system comprises a camera, in particular a high-resolution camera operatively connected to a data processing unit upon which it is performed a particular software routine which allows to identify the actual presence of the at least one support 30 on the culture plate 40. This software routine is in detail initiated when the step of transportation of the at least one first support 30 towards the culture plate 40 by means of the collector is being performed, or has been completed.

The software routine may not only be able to determine whether or not the first support 30 is actually positioned on the culture plate 40, but also whether or not that support 30 is correctly positioned in a predefined position on the culture plate. In an embodiment, such a software routine, when it is detected through the camera that the support 30 has not been positioned on the culture plate 40, or in any case when it is detected through the camera that the support 30 is in a position not corresponding to said predefined position, may cause the activation of an appropriate alarm signal or, alternatively or in combination, may cause the functioning of the device 1 to stop. Additional sensor systems may be present on the device 1 to detect at least the presence or absence of a new support 30 positioned on the culture plate 40.

Alternatively or in combination with the above, the software routine may be configured for allowing to identify the shape and/or the size of the support 30. In a non-limiting embodiment, the data processing unit is configured for operatively and/or logically associating a predefined culture plate 40 with supports 30 of a predefined shape and/or size, and when in use, through the camera, it is detected that the shape and/or the size of the support 30 transported by the collector 19 on the culture plate 40 does not correspond to said predefined shape and/or size, this software routine can cause the activation of an opportune alarm signal or, alternatively or in combination, can cause the stop of the functioning of the device 1.

Still alternatively or in combination with the above, the software routine may be configured for allowing to read an identification code of the culture plate 40, for example, a barcode or an acronym or an equivalent alphanumeric code, and compare such identification code with at least one among: a type of impregnation of the support 30 (e.g., a type of antibiotic), a shape of the support 30 and/or a size of the support 30. In a non-limiting embodiment, such a comparison allows to realize said operational and/or logical association. Similarly, an operational and/or logical association can be realized between one or more containers 20, or one or more types of containers 20, and the culture plate 40, with the same functions as described above, by identifying a shape and/or size and/or a code present on one or more of the containers 20.

Although the software routine may employ several algorithms to accomplish the above-described functions, in a preferred, but not limited thereto, embodiment, it employs at least an artificial intelligence algorithm, which allows to obtain a high detection accuracy and reliability; in particular, such artificial intelligence algorithm may be based on neural networks, in particular convolutional neural networks, to perform a tagging and/or a segmentation of part of the acquired image.

Several relative positions may be assumed between the camera and the culture plate 40; one among these relative positions that wherein the camera is above the culture plate 40, for example being aligned with its axis of rotation. Another acceptable position that where the camera is at a higher height with respect to the culture plate 40 but is positioned next to it.

Where necessary, the camera can be provided with a telecentric lens, which allows to mitigate the negative effect produced by a height difference between the camera optics and the support 30 on the measurement of the shape and/or size of the support 30 itself.

It is noted then that preferably the device 1 comprises at least a vacuum switch configured for performing a measurement of a vacuum exerted by the vacuum holder and/or by the auxiliary vacuum holder 19 v. Vacuum switches of known type can be suitably used in the device 1.

In a preferred embodiment the device 1 comprises a first vacuum switch for the vacuum holder operatively connected to the dispenser 10 or to the auxiliary dispenser 10 w, and a second vacuum switch for the auxiliary vacuum holder 19 v of the collector 19. The first vacuum switch, and when present the second vacuum switch, transmit in use a vacuum signal to the data processing unit. Such a signal is preferably an electric signal, but could also be an optical signal. The data processing unit is preferably but non-limiting thereto configured for performing an electronic comparison between the signal sent from the first vacuum switch (and/or from the second vacuum switch) with at least a vacuum threshold value. This comparison is designed to detect the correct holding of the support 30. Should the signal sent from the first vacuum switch (and/or from the second vacuum switch) indicate a vacuum value exceeding this vacuum threshold value, the action of the vacuum pump may be interrupted, or the vacuum exerted by it may be mitigated, for example through an at least partial closure of a valve, so as not to damage the support 30.

The advantages of the device and method object of the present disclosure are clear in light of the foregoing description; in details, they allow to extract in easy, flexible and rapid way a plurality of supports 30 impregnated with antibiotics for the transfer towards a culture plate 40. The extraction of the impregnated supports 30, which is performed in correspondence of the upper surface of the dispenser 10 is more easily controlled, and requires a less complex servo-actuator system. Consequently, the device 1 herein described is inherently characterized by remarkable reliability.

The device 1 herein described can be automated in an extremely effective way, achieving transfer speeds of impregnated supports 30 from the dispenser 10 to the culture plate 40 significantly faster with respect to those of competitors, in particular if the transfer speed is compared with the constructive simplification, in particular mechanical.

Studies carried out by the Applicant have shown a significant reduction of the filling time of a culture plate 40 with respect to competitors’ devices; this significant reduction is in particular attested on times reduced in the order of more than half, in particular more than ⅔, of the time necessary to obtain a filling of the same culture plate 40. In a particular non-limiting embodiment, the Applicant has achieved a reduction of the time for filling the culture plate 40, going from 35″ to 5″.

The Applicant in particular observes that the specific embodiment of the device 1 and of the method described herein wherein the collector 19 performs a step of simultaneous transportation of a plurality of supports 30 toward the culture plate 40 allows to increment the speed of transfer of the plurality of supports toward the culture plate 40 with respect to the devices of the known art in an even more optimized way.

It is also noted that the device 1 described herein allows to be able to quickly adapt to variations in the supply chain of containers 20, and is consequently extremely flexible in use. In particular, it is noted that the particular technique of extraction of supports 30 from containers 20 accessible from an upper surface and/or however accessible upwards of the dispenser 10 allows, under determined conditions, to perform the extraction of the supports 30 from containers 20 of different type without the need for adaptation of the extractor 18. In particular, the dispenser 10, where present the auxiliary dispenser 10 w, the extractor 18 and/or the collector 19 can be specifically adapted and configured for allowing a readaptation to different supports 30, the operative flexibility of the device 1 is considerably increased, and the latter can be therefore quickly put in a condition to operate with containers 20 produced by different suppliers, in particular having different sizes.

The object of the present disclosure is not limited to the embodiments shown in the attached figures; for this reason, where reference numbers are present in the following claims, such reference numbers will be provided for the sole purpose of increasing the intelligibility of the claims. Such reference numbers therefore have no limiting function.
